Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Can your pupils build a roof that stands the test of time? Use an insightful engineering design project to highlight both materials science and architecture. Scholars either team up or work as individuals to design, create, and test a...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

Climate affects populations in different ways. Scholars research extinct organisms and mass extinctions in part three of the 10-installment Discover Your Changing World series. They create graphic organizers, then fill in the...

Where does the water we use come from? To understand the concept of a watershed, class members study the water cycle and then engage in an activity that simulates a watershed.

Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can form crystals under the right circumstances, and the crystals change in size and shape, depending on...
